MOTOR-SUPPORT FOR SPINNING-HIAGHINES.

Application filed May 25,

T 0 all whom it may concern.

Be it known that I, CLIFTON CORLEY, of Greenville, in the county ofGreenville and State of South Carolina, have invented certain new anduseful Improvements in M0- tor-Supports for Spinning-Machines, of whichimprovement the following is a specification.

This invention relates to the supports for the driving motors ofspinning or twisting machines, or the like, and has for its objects toprovide an improved support to strengthen the machine, to eliminatevibration, to save valuable floor space, and provide a simple, compactconstruction of neat appearance.

Motors for driving these machines have heretofore been mounted onbrackets extending out from the face of the front frame of the machine,and connected by gearing with the driving shaft of said machine, butthis arrangement has been found to produce excessive vibration whichwears out the gearing and drive chains, and is also objectionable in theoperation of the machines. This prior arrangement also takes upconsiderable floor space at the front end of the machine, and obstructsthe space in the aisle between the rows of said machines in the cottonmill.

According to my improvement, the motor is supported on a hanger bracketor cradle, which is suspended from, and rigidly secured to, the ringrails of the spinning machine inside of the end frame, there being adriving connection from the motor shaft to the main shaft of themachine.

In the accompanying drawing: Figure 1 is an elevation of the front endof a spinning machine, with my improvement applied thereto; and,.Fig. 2,a side elevation of the same.

A portion of an ordinary form of spinning machine is shown in thedrawing, comprising a front end frame, 5, having upright posts supportedon the floor of the mill, and longitudinal rails, called ring rails, 6,bolted at their ends to the end frame, 5, and extending to thecorresponding end frame at the other end of the machine, (not shown),for carrying the various spindles, reels, etc., (also not shown), all ofwhich may be of the usual well known construction. According to theusual practice in cotton mills, these spinning machines are arranged inrows, with an aisle located between the adjoining Specification ofLetters Patent.

front end frames of the respective rows, and the machines may be drivenby individual electric motors.

An outwardly projecting bracket, 7, is rigidly attached at its ends tothe two posts of the end frame, 5, and carries the outer bearing, 8, ofthe main shaft, 9, of the spinning machine, on which shaft is mountedthe driving gear or sprocket wheel, 10.

According to my improvement, the electric motor, 11, for driving themachine is supported on a cradle or hanging bracket, 12, formed of anintegral casting having a horizontal bed portion for the motor andupwardly extending webs at either side adapted to be rigidly bolted tothe ring rails, 6, of the spinning machine inside of the end frame, 5.The cradle thus not only serves as a hanger for supporting the motorbeneath the machine, but also acts as a rigid brace for strengtheningthe ring rails of the spinning machine, and greatly reduces thevibration. The motor shaft is provided with a sprocket gear, 13, whichis connected by a drive chain, 14, with the sprocket gear, 10, on themain shaft of the machine.

My improvement also has the advantage of saving valuable floor space, asthe motor is out of the way beneath the spinning machine, andobstruction to the passage way through the aisle is thereby avoided. Italso adds to the useful life of the drive chain, as it preventsvibration, which causes a cutting out of the chain.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a spinning machine, the combination,

with the end frame, ring rails and main shaft, of a hanger bracketrigidly secured and suspended from the ring rails, a motor mounted onsaid bracket, and a driving connection therefrom to the shaft of saidmachine.

2. In a spinning machine, the combination with the end frame, ring railsand main shaft, of a hanger bracket rigidly secured and suspended fromthe ring rails, inside of the end frame, a motor mounted on said bracketand having a shaft extending out beyond the end frame, gears mounted onsaid shafts outside of the end frame, and a driving connection for saidgears.

3. In a spinning machine, the combination with the end frame, ring railsand main shaft, of a hanger bracket rigidly secured and suspended fromthe ring rails, a motor mounted on said bracket and having a shaft,gears mounted on said shafts, and a drive chain eonnecting'said gears.

4. In a pinning machine, the combination With the end frame and ringrails, of a hanger bracket formed of an integral casting having'ahorizontal bed for a motor, and upwardly extending Webs at both sidesrigidly fastened to the ring rails inside of 10 the end frame.

In testimony whereof I have hereunto set In hand.

y CLIFTON CORLEY.
